Hi Everyone,

I’m a bit confused about the following fact:  
I have a MainMenubar with an Menuitem e.g. “Details” and named it to “mDetails”. I set AutoEnable to False.

If a row in a Listbox is selected, mDetail should set to Enabled = True, else False.  
[h]My Code[/h]

`Sub Change()
If Me.ListIndex > -1 Then
  mDetails.Enabled = True
Else
  mDetails.Enabled = False
End If
End Sub`

I work with Xojo Version 2014.2 and compile a Cocoa Application!

How to get it working?

Best regards!

You will need to enable and disable your menu item in the enableMenuitems event of the screen

Hi Roger,  
thats laborious, but it works fine. I created a BooleanVariable, called EnableDetails!

`Sub Change()
If Me.ListIndex > -1 Then
  EnableDetails = True
Else
  EnableDetails = False
End If
End Sub`

Thank You!

Just put this code in the EnableMenuItems event of the window:

```auto
mDetails.Enabled = ( Listbox1.ListIndex > -1 )
```

Replace Listbox1 with the name you gave your listbox in the window editor.
